[PATCH v4 1/8] define ksym_flags enumeration to represent kernel symbol flags

[Siddharth Nayyar <sidnayyar@google.com>]

Symbol flags is an enumeration used to represent flags as a bitset, for
example a flag to tell if a symbol is GPL only.

The said bitset is introduced in subsequent patches and will contain
values of kernel symbol flags. These bitset will then be used to infer
flag values rather than fragmenting ksymtab for separating symbols with
different flag values, thereby eliminating the need to fragment the
ksymtab.
